FRITZ GOEDECKE, OF TELTOW, NEAR BERLIN, GERMANY.

SPECIFICATION forming part of Letters Patent No. 773,285, dated October25, 1904.

Application filed May '7, I904. erial No. 206,876. (No model.)

To all whom, it natty concern:

Be it known that I, FRITZ GroEDEoKE, chief gardener, a subject of theKing of Prussia, Emperor of Germany, residing at Teltow, near Berlin, inthe Kingdom of Prussia and Empire of Germany, have invented certain newand useful Improvements in Devices for Utilizing the Power of the Wavesof the Sea, of which the following is a specification.

This invention relates towave-motors or devices for the utilization ofthe power produced by the undulations of waves of the sea; and itconsists of a vertically-movable float to drive in one direction ascrew-spindle, with details of construction hereinafter specified.

Referring to the drawings, in which like parts are similarly designated,Figure 1 is an elevation of the device, partly in section. Fig. 2 is apartial vertical section showing the actuating parts on a larger scale,and Fig. 3 is a section on line on m, Fig. 2.

The device comprises a frame composed of "cross-pieces z', of iron orother suitable material, connected by rods or guides h. In the frame isjournaled a screw-spindle f, having a thread of high pitch to be rotatedin one direction and from which any suitable mechanism is driven in anydesired manner and here shown, for example, as a worm w, driving aworm-wheel n on a shaft 01/.

On the screw-spindle f is a hollow body or ball (0, provided with acentral tube 9, surrounding the spindle, and with eyes 6, through whichthe rods it pass. At the lower end of the tube g is a clutch element 6,having teeth.

at its upper end that engage complementary teeth on a sleeve 0,surrounding the spindle and free to move thereon. One or more pins cl,fixed in the sleeve 0, take into the groove of the spindle f.

The frame is secured in the water, and the ball floats on its surface.

The waves lifting the ball cause the lower clutch element to engage theteeth on the sleeve 0, thereby preventing this sleeve from rotating,while the vertical movement of the ball and sleeve will cause thespindle f to rotate by reason of pin or pins 6! moving vertically in astraight line. When the ball descends, the clutch element?) isdisengaged from the sleeve 0, and the latter is freeto rotate as itdescends, being guided by the pin (Z in the thread in spindle f.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is

1. The combination with a screw-spindle, of a float guided to movevertically, a clutch, and a sleeve on the spindle adapted to be engagedby the clutch and drive the spindle, substantially as and for thepurposes set forth.

2. The combination with a screw-spindle, of a float guided to movevertically, a clutch element secured to the float, a sleeve on thespindle and a pin fixed in the sleeve to engage the thread of thescrew-spindle, whereby said spindle will be rotated when the float islifted, substantially as and for the purposes set forth,

3. The combination with upright supporting-rods and a spindle having ahelical groove
